it is possibleto get herpes the way u describe if only the girl had an outbreak and ur penis came in contact with her vagina. the only way for sure is to go get tested for herpes, irritated penis does not sound like herpes at all. The first symptoms of herpes will cause visible sores or blisters. hope this help
Nicky,
You need to ease up, listen to me, you were never at a risk, you can't get some thing that you weren't exposed to
Your symptoms, discomfort, issues etc are all due to anxiety, stop reading about HIV, it's not the problem with you, YOU CAN'T GET HIV THROUGH THE KIND OF INCIDENCE YOU HAVE MENTIONED ABOVE !
See a shrink, it'll help you to relieve you of your irrational fears
